| Abstract: | This work aims to fabricate the undoped and doped polyvinyl alcohol (PVA)/carboxymethyl cellulose (CMC)-blended polymers with ZnCo2O4-CdS, multi-walled carbon nanotubes (MWCNTs), and polyaniline (PANI) to utilize them in many optoelectronics and energy storage fields. The structure of the dopant and the blended polymers has been investigated. The sample with 0.25 wt% PANI has the greatest absorption. The lowest direct and indirect energy gap values are 5.59 eV and 4.96 eV, respectively, accomplished with a PANI concentration of 0.25 wt %. The optical dielectric constant, optical conductivity, and energy loss functions of the samples improved. Compared to the unfilled sample, the fluorescence intensities of the filled samples are lowered. The filled blended polymer including ZnCo2O4, CdS, MWCNTs, and 0.2 wt % PANI exhibited the greatest dielectric constant (ε′, 26.67 at 1 kHz) compared to the other polymers (12.47–19.48 at 1 kHz). Loaded PVA/CMC composite polymer with ZnCo2O4, CdS, MWCNTs, and 0.15 wt % PANI displayed the greatest energy density values (0.01091 J/m3 @ 1 kHz). The Nyquist plots (Z' against Z": real against imaginary parts of the electric impedance) for all blended polymers suggested that the insertion of fillers affected the ionic conductivity of the different blended polymers.
